Data Inversion Techniques

2. The method of claim 1, wherein the modulation scheme further comprises at least four physical levels, the modulation scheme relating each physical level of the at least four physical levels with a respective logic level of the at least four logic levels.

9. The method of claim 7, wherein the modulation scheme further comprises at least four physical levels, the modulation scheme relating each physical level of the at least four physical levels with a respective logic level of the at least four logic levels.

14. The apparatus of claim 13, wherein the modulation scheme further comprises at least four physical levels, the modulation scheme relating each physical level of the at least four physical levels with a respective logic level of the at least four logic levels.

19. The method of claim 18, wherein the modulation scheme further comprises at least four physical levels, the modulation scheme relating each physical level of the at least four physical levels with a respective logic level of the at least four logic levels.

21. The method of claim 18, wherein an initial physical level corresponding to an inverted data symbol of the one or more data symbols is located at an opposite side and at an equal distance from the signal axis as a final signal level corresponding to a re-inverted data symbol associated with the inverted data symbol.
